T ll wh it may m involves the use of an internal combustion Be it known that I, CARL Rheum, a subengine operating seicl feeding means (gen ject of the German Emperor, and resident erally pumps) and governed by the operaof Berlin, Germany, have invented certain $1011 0f the gas P oducernew and useful Improvements in A pararus n ihe drawin 1 indicates 11 Ch mb in for Conveying Liquid Fuel, of w ich the f inch the exp osive -miXture admittefi foliowing 13 a spemficaigion, tnrough the p1P6 2S thOI'OUghly COllSilIklEd The conveyance of inflammable liquids at of i (9X06 t that (such as gesolene) through ipes has been fiofitalned 1Z1 Q 5 mlXiJlP itself) e accomplished, for the sake 0 safety, in the g w g from th s?

In either event, the inflammable liquid would come in Contact with air, and this I d ir to v id, son the mixture fed to the producer 1 should A typical example of an apparatus m; not be properly proportioned and therefore bodying my present invention is shown in lack explosive cyialities, the motor 13 Woulii the accompanying drawings, in Which---- stop as it won (1 receive an ineflicient fuel Figure 1 is a general View of the plant, .mixture, Similarly, if the flame within. the with parts in section, and Fig. 2 is a side producer 1 should. accidentally become ex elevatlon, with parts in section, showing tinguished, thus interrupting the formation chiefly the motor and the gas producer. of inert $8, the. motor would stop since Briefly described, the apparatus comthere wou d be no ignition. prises a producer of inert gas, together with The driving of the pumps 4 and 11 from means for feeding the'gas and liquid, the the motor 13 may be accomplished in any operation of one or both of said means, bcsuitable manner, for instance by a belt 15 ing dependenc upon that of the producer. engaging the fly Wheel 14 and a pulley 1? The; pzcicrred embodiment of this inveniioe; e couet-ershaft- 1%. This shaft also oer ries pulleys 18 and 19 from which belts 20 and 21 lead to the pulleys 22 and 23 on the shafts of the pumps 4 and 11 respectively.

The countershaft 16 with its connections may be termed means for actuating the device (such as the pump 4) for feeding the gas generated in the producer, and may also be termed meansfor actuating the device (such as the pump 11) for withdrawing liquid from the receptacle. The motor thus forms a controller, influenced by the producers action, for governing the operation of said means.

It will there-f fl'e be seen that in the form of, my invention illustrated by the drawing, any interruption in the production of the inert gas will cause an automatic stoppage of the gas pump 4 and of the liquid pump 11, thus avoiding the sources of danger hereinbefore mentioned.

Certain features shown in my present applioation are claimed generically in my application Serial No. 516976 filed concurrently herewith.

The operative connection between the pumps 4 and 11 (formed by the shaft 16 and belts 20, 21) is a decided advantage in that it insures the preservation of a proper pressure in the receptacle 9 whenever liquid is withdrawn therefrom through the pipe lO. For, as soon as the pump 11 is operated to withdraw liquid from ,said receptacle, the pump 4 is also operated to feed the proper amount of inert gas into said receptacle through the pipe 7, thus maintaining a practically constant gas pressure in the receptacle.

I claim as my invention:

1. The combination of a gas producer, means for leading an explosive mixture thereto, a device for feeding the burnedgas from the producer, an internal combustion motor for actuating said device, and means for leading to said motor, as its working medium, a portion of the said explosive mixture.

2. The combination of a gas producer, means for leading an explosive mixture thereto, a device for feeding the burned gas from the producer, an internal combustlon motor, the ignition of which is controlled by the operation of the producer, for actuating said device, and means for leading to said motor, as its working medium, a portion of said explosive mixture.

3. The combination of a gas producer, a

device for feeding the gas produced therein,

means for actuating said device, and a controller, influenced by the producers action, for governing the operation of said means. 4. The combination of a gas producer, a suction device, connected with the outlet of the producer, for withdrawing gas there from and feeding it forward, means for actuating said device, and a device controlling said actuating means, said controlling device being exposed to, and operated by, the heat of the producer.

- 5. The combination of a gas producer, a

vice, and an igniter for said motor, which igniter extends into the producer so as to be exposed to the heat thereof.

7. The combination of a gas producer, a suction device, connected with the outlet of the producer, for withdrawing gas therefrom andfeeding it forward, means for leading an explosive mixture to said producer, an internal combustion motor, the ignition of which is dependent upon the operation of the producer, for actuating said suction device, and means for leading to said motor, as its working medium, a portion of the said explosive mixture.

8. The combination of a gas producer, a device for feeding gas from the producer, an internal combustion motor for actuating said device, and'an igniter for said motor, controlled by the heat of the producer.

9. The combination of a gas producer, a device for feeding as from the producer, an internal combustion motor for actuating said device, and an igniter for said motor, exposed to the flame of the producer.

In testimony whereofI have hereunto set my hand in the presence of two subscribing witnesses.
